PTP1B Inhibitory Secondary Metabolites from an Antarctic Fungal Strain
Chemical investigation of the Antarctic lichen-derived fungal strain Acremonium sp. SF-7394 yielded a new amphilectane-type diterpene, acrepseudoterin (1), and a new acorane-type sesquiterpene glycoside, isocordycepoloside A (2). In addition, three known fungal metabolites, (-)-ternatin (3), [D-Leu]...
